Eastwood's latest "Unforgiven" is Clint Eastwood's best film in years, both as a director and an actor. He plays an ex-gunman who goes back into the killing business and heads off to rub out two bad cowboys who've cut a woman's face up. The real tension in the movie is between the fanciful mythology of the west and the squalid reality. Great performances by Gene Hackman, Richard Harris and Morgan Freeman keep the movie remorseless and honest, at least until a final shootout that feels somewhat Hollywood-phoney. R. ***. Vaclav Havel, who recently resigned as president of Czechoslovakia, began work on "Temptation" when he was a political prisoner in that country. The play is a version of the Faust legend, and the affiliation of the Mephistopheles character is deliberately ambiguous. Is he the devil, an informer, or the government? Havel's point seems to be that there's no difference. The Bowman Ensemble, which is presenting "Temptation" tonight and tomorrow at 8 p.m. outdoors at McDonogh School in Owings Mills, is to be commended for a production that is both intelligent and entertaining. Tickets are $10. Call (410) 243-3676.
